Safety Warnings Specific For Wire Brushing Operations; Additional Safety Instructions - Hilti DAG 450-S Mode D'emploi

b) The guard must be securely attached to the power
tool and positioned for maximum safety, so the
least amount of wheel is exposed towards the op-
erator. The guard helps to protect operator from bro-
ken wheel fragments, accidental contact with wheel
and sparks that could ignite clothing.
c) Wheels must be used only for recommended ap-
plications. For example: do not grind with the
side of cut-off wheel.Abrasive cut-off wheels are
intended for peripheral grinding, side forces applied
to these wheels may cause them to shatter.
d) Always use undamaged wheel flanges that are of
correct size and shape for your selected wheel.
Proper wheel flanges support the wheel thus reduc-
ing the possibility of wheel breakage. Flanges for
cut-off wheels may be different from grinding wheel
flanges.
e) Do not use worn down wheels from larger power
tools. Wheel intended for larger power tool is not
suitable for the higher speed of a smaller tool and
may burst.
5.5 Additional safety warnings specific for abrasive
cutting-off operations
a) Do not ²jam² the cut-off wheel or apply excessive
pressure. Do not attempt to make an excessive
depth of cut. Overstressing the wheel increases the
loading and susceptibility to twisting or binding of
the wheel in the cut and the possibility of kickback or
wheel breakage.
b) Do not position your body in line with and behind
the rotating wheel. When the wheel, at the point
of operation, is moving away from your body, the
possible kickback may propel the spinning wheel
and the power tool directly at you.
c) When wheel is binding or when interrupting a cut
for any reason, switch off the power tool and hold
the power tool motionless until the wheel comes
to a complete stop. Never attempt to remove the
cut-off wheel from the cut while the wheel is in
motion otherwise kickback may occur.Investigate
and take corrective action to eliminate the cause of
wheel binding.
d) Do not restart the cutting operation in the work-
piece. Let the wheel reach full speed and carefully
reenter the cut. The wheel may bind, walk up or kick-
back if the power tool is restarted in the workpiece.
e) Support panels or any oversized workpiece to
minimize the risk of wheel pinching and kickback.
Large workpieces tend to sag under their own weight.
Supports must be placed under the workpiece near
the line of cut and near the edge of the workpiece on
both sides of the wheel.
f) Use extra caution when making a "pocket cut"
into existing walls or other blind areas. The pro-
truding wheel may cut gas or water pipes, electrical
wiring or objects that can cause kickback.
5.6 Additional safety instructions for sanding
operations
a) Do not use excessively oversized sanding disc
paper. Follow manufacturers recommendations,
when selecting sanding paper. Larger sanding pa-
per extending beyond the sanding pad presents a
laceration hazard and may cause snagging, tearing
of the disc or kickback.
5.7 Safety warnings specific for wire brushing
operations
a) Be aware that wire bristles are thrown by the
brush even during ordinary operation. Do not
overstress the wires by applying excessive load
to the brush. The wire bristles can easily penetrate
light clothing and/or skin.
b) If the use of a guard is recommended for wire
brushing, do not allow any interference of the
wire wheel or brush with the guard. Wire wheel or
brush may expand in diameter due to work load and
centrifugal forces.

5.8 Additional safety instructions

5.8.1 Personal safety
a) Wear ear protectors. Exposure to noise can cause
hearing loss.
b) Always hold the power tool securely with both
hands on the grips provided. Keep the grips dry,
clean and free from oil and grease.
c) Breathing protection must be worn if the power
tool is used without a dust removal system for
work that creates dust.
d) Improve the blood circulation in your fingers by
relaxing your hands and exercising your fingers
during breaks between working.
e) Avoid touching rotating parts. Switch the power
tool on only after bringing it into position at the
workpiece. Touching rotating parts, especially rotat-
ing insert tools, may lead to injury.
Always lead the supply cord and extension cord
f)
away from the power tool to the rear while work-
ing. This helps to avoid tripping over the cord while
working.
g) Children must be instructed not to play with the
power tool.
h) The power tool is not intended for use by children,
by debilitated persons or those who have received
no instruction or training.
i) WARNING: Some dust created by grinding, sand-
ing, cutting and drilling contains chemicals known
to cause cancer, birth defects, infertility or other
reproductive harm; or serious and permanent res-
piratory or other injury. Some examples of these
chemicals are: lead from lead-based paints, crys-
talline silica from bricks, concrete and other masonry
products and natural stone, arsenic and chromium
from chemically-treated lumber. Your risk from these
